Propeller capable of improving steering effect

Abstract

The invention belongs to the technical field of marine engineering, and particularly relates to a propeller capable of improve the steering effect. The propeller comprises a propeller shaft, two endsof the propeller shaft are connected with propeller hubs through a shaft disc, the propeller shaft is provided with a plurality of groups of hydraulic mechanism groups, each group of the hydraulic mechanism groups comprises two hydraulic mechanisms, each hydraulic mechanism is provided with an inner meshing gear hydraulic pump, each gear hydraulic pump is connected with a power supply system through a motor, each gear hydraulic pump is internally provided with a hydraulic oil circuit, each hydraulic oil circuit is connected with one end of a piston connecting rod, and the other end of the piston connecting rod is connected with the propeller hubs and is located on the left and right sides of the propeller hub. The propeller capable of improve the steering effect can effectively improve thesteering effect in the process of ship navigation, the control method is exquisite in design, the control precision is high, the energy utilization rate in the operation process is high, and the propeller is especially suitable for medium and large ships; compared with the prior art, the structure is simple and flexible, the layout is compact, the shipping cost can be effectively reduced; and thedesign of the system structure of the propeller is novel, the propeller is easy to realize and suitable for popularization and use.

Description

technical field [0001] The invention belongs to the technical field of ship engineering, and in particular relates to a propeller for improving rudder efficiency. Background technique [0002] A marine propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or is similar to a helical surface A marine propeller. Under the premise that the internal combustion engine is still the mainstream power device of the ship, the position of the propeller is almost unshakable. However, since the second half of the last century, with the continuous development of material science and fluid mechanics, various new ship propellers have come out one after another. challenge. At the same time, with the increasing informatization and automation of port transportation, higher requirements are placed on the ...

Problems solved by technology

In this context, various improved propellers that pursue high efficiency have emerged, such as the adjustable pitch propeller CPP that can be traced back to the 1920s and 1930s, the contra-rotating propeller CRP equipped with real ships in 2004, As well as the high skew propeller HSP developed for special needs, etc., but there are very few people who can really improve the rudder effect. Among them, although the power configuration of multi-engine and multi-propeller can effectively prevent the cavitation phenomenon and improve the rotatability of the ship, but High energy consumption and complex power system; although the pod propeller has good maneuverability, but the main engine is arranged outside the hull, the safety is not strong, and the transmission power is not high, so it cannot be applied to large ships
